Lasker–Blackburne, from their 1892 match in London — Emanuel Lasker grinds down Joseph Blackburne in a Queen's Gambit Declined, illustrating his maxim that king-side attacks in this opening “have usually little hope of success” while the real fight lies in the centre and on the queen's wing. Lasker annotates his own win in Common Sense in Chess (1896); his public-domain notes follow.
5…c6On account of the last move which is more or less forced (not to allow Q Kt - Kt 5) the development chosen by Black is not advisable.
11…f5Attacks on the K side in this opening have usually little hope of success. An inspection of the position will show that the K side does not present weaknesses that could be assailed. The fight is, therefore, in the centre and on the Q side.
15.Qc2Black has, with his 11th move, stopped the advance of the White K P. The White Q is therefore now available for the Q's wing.
18.Re1White intends a Q side attack; and, therefore, makes first preparations to take advantage of any forward movement that Black might undertake on the K side, beginning with P - B 5.
24…dxc4White threatened now P - B 5, followed by P - R 5 and P - R 6, to establish a dangerous passed Pawn at B 5.
29.Ra1The object of White's attack was to keep the Q R P back, which is now indefensible.
35…Rc7The attack has now succeeded. White has the advantage of a Pawn plus on the K side. What remains is to convert this into positional superiority — not an easy process, as still there are hardly any assailable points in the Black camp.
46.h5The decisive manoeuvre. If the P is taken, the two isolated R Ps will be a splendid object of attack, well worth the sacrifice.
